Sounds exactly like me as a child...balance probs and all. I was awake and eating right after my tonsil and adenoid op at 4 years old too! Had my first concussion at 7/8 - knocked myself out on a playground and had a nice head egg, but didn't complain so my parents assumed I was fine...then I puked right through the back of the car not long after! Hehehe!

My DD has a high pain tolerance but without the balance probs and without being prone to accidents like I was...she gave her head a huge whack yesterday and she just rubbed it and walked away...has split her lip/mouth open on countless occasions on her broken tooth (broke it before she turned one...no idea how!) and been bleeding everywhere and never batted an eyelid. She's fearless too, which is what worries me! :-P
